Today BP announced that the CEO Tony Hayward would leave his post in October and be replaced by Bob Dudley.

Will that solve BP's problems? I don't think so, because Tony Hayward is not the only one to blame for the disaster. I'm not saying that he didn't make any mistakes, because he did. But Tony Hayward is not BP, as BP is not a one-man show.

Questions remain: Where were his advisers? Did he have any? Did he listen to them? Or was he surrounded by apple-polishers?

Where were BP's press, PR and marketing departments?

BP needs to look at its organizational culture. Is it still old-style command and control? How about the empowerment of employees?

Replacing the CEO is not enough, BP is well-advised to adopt an entrepreneurial culture embracing all employees.
